Hey guys! The dev. team let us know that they are working on a method to allow players to rejoin their instance raid party after being disconnected, and that this should be implemented by patch 1.19! Hurray!
In regards to the loot system, we are working on implementing a system similar to other MMOs in the future. I also did some digging and saw that we responded twice to this question! Here they are so that you won’t have to dig as far back as I did. See, I’m nice too! :3
